I've been in PaddyPower when a bloke with wads of notes was betting on greyhounds and seeing them bolt up. He must've won 10k just when I was in there, and I'd seen him in there doing the same thing several times before.Nobody forced that person to gamble 23k in 20 minutes, the bookies aren't moral guardians, they provide an optional service. If this person had made a massive profit on their investment would they have moaned about the bookies?
A week later I went back and the bloke behind the counter had been sacked. The manager was there doing the job and he explained to me that the staff member had been accepting these huge bets instead of ringing them through, knowing that the punter had a warm source at the track. You can bet your arse that William Hill would have done exactly the same thing.
So they are quick to ensure large bets are NOT taken when the punter knows his onions, yet some clueless addict off the streets is allowed to jizz his money away?
